An argument about whether to get a dog turned into a fight that involved a gun last week for one Robertson County couple.

Sheriff’s deputies were called to an address on Hyde Road near Springfield in response to the domestic dispute Wednesday.

They talked to the victim, who said the trouble began when his wife, Carol Nixon, 58, started arguing with him about getting a dog, according to an affidavit from the Robertson County General Sessions Court Clerk’s Office.

The man said the situation escalated, and he went into the master bedroom to get away from his wife, but she followed him, the affidavit said.

He ended up in the bathroom, where Nixon again confronted him, this time with a .38 revolver, the affidavit said.

As the couple continued to argue, Nixon held the gun, which placed her husband in fear of injury, the affidavit said.

The man told deputies that he was able to grab Nixon by the forearms during the argument and disarm her, the affidavit said.

Nixon was able to grab a tooth brush holder at that point and “struck him in the mouth,” the affidavit reads.

The victim had marks on his hands and face as well as a busted lip, the affidavit noted.

Nixon was charged with aggravated domestic assault, booked into the Robertson County jail Thursday morning and was being held Tuesday on $20,000 bond, according to the Robertson County Sheriff’s Office website.
